Gravitation
Gravitation is the force of attraction between two objects in the universe. Gravitation may be the attraction of objects by the earth.
This force is proportional to the product of masses of the objects and inversely proportional
to the square of the distance between them. It is independent of the medium.
Gravity
Gravity is one of the most basic forces in the universe. It plays a fundamental role not only in the structure of our solar system but also in the way objects behave on Earth.
Eg:- If a body is dropped from a certain height, it falls downwards due to earth’s gravity. If a body is thrown upwards, it reaches a certain height and then falls downwards due to the earth’s gravity.
Gravitation may be the attraction between objects in outer space.
Eg:- Attraction between the earth and moon.
The attraction between the sun and the planets.
Universal law of gravitation:
The universal law of gravitation states that ‘Every object in the universe attracts every other object with a force which is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.’
The strength of the gravitational attraction between two objects depends on two factors:
1. How big the objects are (how much mass they have) and
2. How far apart they are.

Sir its depend on size as a force?
At 11:15 u wrote a formula its better ki u can write F=GM²/d²
Students that see his video before one day of exam are legends................ Salute to them.

Who were watching this during online class. 😂😂😂
I think instead of apple if coconut will fell on newton's head that will more benficial for us
Yes bro at least he go into coma
@@MRKREX-vb6fm wth bro 🤨😑
Yes it actually benificial
I am very thankful to you sir because I read this Lesson many times and I have tried to make understand this lesson in my school also but then also I don't understand this lesson after seeing your I understand this lesson very carefully. sir your explanation is very nice better than my school teacher also😊 I'm 100%sure that if you teach your students like this your channel will go ahead and definitely it will reach at the highest study channel may in all over India or a entire world if you do work hard and I was so because I understood this lesson very nicely ☺thanks a lot sir😊😊😊☺☺☺☺😊🙂☺🤗😇😇😇

thanks sir for this video
the video was very nice
u r very helpful for the student again thanks
Sir thank you so much i can understand your teaching only
Sir pls make a video on Maas and waight
Weight ki spelling galat hai
This I've noticed always, anyone who is really intelligent, brilliant, knowledgeable always try their best to make understand to others also. They are confident while teaching. Like,
sir always teach best on a specific topic, because they know it very well
Good
Absolutely correct
I want to know that who you solved that gravitational force between earth and moon
Thank you so much sir
Thank u so much sir
your steps truly helpful.. Thank you sir
Yes reallyy
I love you
Its is soo easy to understand sir! pls make the continuation part nd i hope you get more subscribers!dron study rox!
Thank you Sameer !! :)
yaa I'm agree with you

Hii
Sir 2 big objects me jb attraction force h aur 2no objects ki gravitational force direction bhi 1 h to ayk dosry ki tarf move kun nhi krty????
Thank you so much sir.Your methods and way to explain is very nice

Chal oo
sir ur explanation is very excellent......😘😘😘😘😘😘😘😘
Explain why force aatraction is directly proportional to the product of its mass and is inversely proportional to the product of it's distance (universal law of gravitation )
sir G ka value sabse pahle kaun scientist ne calculate kiya tha ?
very nice explanation
This is to dronstudy, nicely explained universal law of gravitation, thanks sir.....
Wow that's a great explanation sir. Thank you
Sir thank you so much... Bht achcha explain kiya 🙏🙏
Your welcome, Aadila Shafin.
great explaination 👍
poorvi nayyar hay
💯
Sir how to find the value of G i.e. universal gravitational constant ? From where does it came?
Nice question bro
😍wow sir very nice explaining
Thank-you so much 😘😘😘
Awesome video sir.how can someone teaches so well. Sir superb fantastic and brilliant. Sir please upload some questions related to gravitation.
Really sir
Must say that you teach marvellous. You explain complicated things very easily, please make more videos .
Thank You Akanksha!! :)
Very helpful for my exam .............. 2 gud
You give me more knowledge about gravitation 👌👍
I loved your teaching method Sir 👍👍👍👍
Sir your sound is very brilliant
hi sir! this helped me a lot.... thank you so much
but one thing i didn't understood....
that... 1x1=4 ( 1 multiply by 1=4 )
how??
plzz explain briefly..
:)
See the value of d^2 in the denominator is (1/2)^2 =1/4. If we want to calculate further we have to take the 4 of 1/4 in the numerator.So for doing that 4 has to be multiplied with the numerator
ohh... thank you so much bro.... :)
We have done the resiprocal of the denominater
Hahahhaha so simple question this method can be done by Ramanujan theory
Rishavneet Kaur
Thanku sir bottom of my heart 🤗🤗☺☺
Nice teaching
Before in don't know about gravitation now seeing this video I came to know that what is gravitation. Thank you, and upload more videos......😁😀😎😘😉
Sir I am student of 9th standard so l ask a question about the keplar law of pelentry motion
Hello Inder pal this is our sample video for full video Please call on 9026272829
Sir I love the way you explain.
Hats off to your knowledge.😀😀
THANK YOU !!!☺
Physics would have been much simpler if the tree itself had fallen on Newton instead of apple.
14:53 ye y2 half kaise hogaya sir samaj nhi aya
Thanks Sir 😇
Sir I was not able to understand the chapters. Your video made it very simple to understand.
Thank you very much.

Sir universal law of gravitation can takes place between two elephant??
I am from Tripura! I like the way you teach Sir.
Thank u soo much for ur explanation sir... Keep uploading ur vedios. I'll watch all ur vedioss

Sir u speak very fast 😂🤣
By the way nice vedio.....
Keep it up🥰
sir agar force mass pe depend karta hai toh jis ball ka mass zyada hoga woh zyada force lagaye gi but apne bola ki equal force lagta hai? Hos is that possible?
very nice explanation everything is cleared... thnx sammeer sir u are really good teacher...
Fantabulous✓
I understood it very well :)
Really mind blowing explanation 👌👌👌👌
I saw a number of videos but this one is the best.. Thanks a lot sir

So how magnates are attracted each other comparing to two bolls both the cases earth attracts the object?
Nice sir it clear my all doubts and tomorrow is my paper
it was a good video to understand..nicely done
nic for exam
If earth and moon both feels the gravitational force then why not they collide with each other
@@chandnimishra9009 Because in space there is a law that a large mass object makes the less mass object revolve
Thanku sir
U explained it very well
I understand it easily

English sikhle 😕😕
What is action reaction pair
These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.
